Ok, couple of pics of the construction site and building plans.
This is the view from planned Settling-Tank and Bog towards the main pond.
Frontal view of Settling Tank and Bog, main pond will be on the right.
The front of the office. The extension for toilets is not drawn in yet.
The side/main entrance of the office.
Top view of the office. Again without the 2x5meter extension at the top left of the office for the toilets.
Thought the blocks where 6x6, but it works out to 5x5 according to the drawings. So total pond system will be 20meter, not 24.
The office front will be in sand-color/yellow brickwork.
With that in mind, large rocks/stones and pavement should really work out well.
Front wall of the pond without straight 90' corners except on the left back side, where the bog/settling-tank face a walk-way around the factory for maintenance.
Settling Tank I plan on using concrete prefab rings that they commonly use for underground wastewater tanks. 200cm diameter, level with the bog.
Grow-out tank about 20cm lower, water cascading over flagstone into the Grow-out.
From there, another 20cm lower same idea into the main pond.
3 drains, all going into the settling-tank.
2 bottom-drains and 1 skimmer.
I am planning on a minimum of 3 pumps similar to what I have from Settling tank into the Bog.
Maybe 1 closed loop for some waterfalls in the main pond.
